Greenland Ice Sheet Slipping Under Hottest Temperatures Ever Recorded
According to reports from Weather Underground, Greenland experienced its hottest temperature ever recorded on July 30th, 2013. The new record, 78.6 degrees Fahrenheit, was measured at Maniistoq Mittarfia on the western coast of Greenland near Baffin Bay. The event occurred during a period of rapidly increasing Greenland melt as a high amplitude wave in the Jet Stream surged over Greenland, pulling warm air up from the south.
This southerly flow set up conditions for what is called a foehn event — a warm, dry airflow that occurred in the slopes of Greenland’s western mountains. This associated warm flow amplified heat over a broad region of Greenland, creating 2013’s largest melt spike, even as it set new temperature records. The previous record was 77.9 degrees (F) which was set in 1990 at Kangerlussuaq on July 27th.
As Greenland was experiencing its hottest foehn wind event ever recorded, a number…
